What are the barnacles of sea creatures? Why does it make whales and turtles so painful?

It's a parasitic organism that feeds on the blood of sea creatures, so whales and turtles can't get enough of it.

A marine parasitic animal. This kind of thing can parasitize the back of animals, and over time it will affect the movement of these animals and make them die.

Which is the scariest animal in the ocean? I believe that many friends will think that it must be a great white shark.

Or killer whales. Countless marine animals are dying because of them!

What are barnacles? It and whales.

What is the relationship between them?

1. Super viscous glue barnacles

Barnacles (scientific name: balanus), barnacle family, barnacle genus, are clusters of grayish-white, calcareous shell arthropods attached to rocks by the sea.

It is shaped a bit like a horse's teeth, so people who live by the sea often call it Huifeng"Horse teeth, barnacles have a hard shell on the body surface, the stalk is degraded, and the shell plate of the head is thickened and healed. Barnacles can be attached not only to the reef, but also to the hull of the ship, and their adsorption power is extremely strong. After each barking, barnacles secrete a sticky barnacle primary gum, which contains a variety of biochemical components and strong adhesion, thus ensuring its strong adsorption capacity.

2. The relationship between barnacles and whales is parasitic

Barnacles will have an action before finding the host to adsorb, which is to use their tentacles to temporarily fix on the host first. The purpose of this action is to first perceive whether the host's environment is conducive to their own survival. Since most of the large cetaceans are mainly krill.

For food, and the main food of krill is precisely plankton.

Therefore, the whale's diet coincides with the barnacle's food, so the whale is one of the best choices for its adsorbs. Secondly, large cetaceans swim more slowly, which is conducive to their adsorption, so almost every large cetacean has barnacle parasitism on its body.

Postscript: Although barnacles have no effect on rocks or whales, if they are attached to the bottom of the boat in large quantities, they can accelerate the corrosion of the metal at the bottom of the boat. As a result, many fishermen use fire to the bottom of the boat or apply toxic substances to the bottom of the boat to get rid of barnacle parasitism.

Barnacles are arthropods with a calcareous shell attached to the rocky lead stones of the seashore, often forming dense communities.

Barnacles and whales play with each other in the process of evolution, barnacles have evolved a turtle plate structure, this structure can be firmly anchored in the whale, and has penetrated the whale's **, into the whale's fat layer, and the tooth fixation method is very similar, that is to say, the barnacle has become one with the whale, no matter how vigorously the whale exercises, the barnacle will not fall.

When it first sticks to the whale**, the barnacle can not stick to the host very firmly, the main stimulus is that the viscosity of the glue is not strong, this is a trial and error opportunity for the barnacle, once the barnacle finds that its parasitic excitation position is not comfortable or uncomfortable, the barnacle will re-choose the position, and even re-choose the host.

Barnacles are a parasitic organism of the ocean. Its relationship with whales is that of parasitism and parasitism.

This is an arthropod in the ocean, and they often attach themselves to the body surface of whales to survive in a parasitic relationship.
